Implementing Bluetooth features to Print on a bluetooth printer in Xamarin Forms App

I'm trying to avail Bluetooth features in my Xamarin Forms App to Print on a bluetooth printer but can't get it working.
Even not able to search devices and pair.
I tried below two plugins but none of them works for me.

Thanks for quick response.
Just had words with provider and confirmed Bluetooth version. Its 2.0, so obviously its not BLE.
Can you please provide me some snippets of codes to connect with Classic bluetooth and print on a Bluetooth Thermal Printer.
Thanks

@ClintStLaurent said:"doesn't work" is very vague. Is it throwing an exception? Not connecting... You could be 99% there and just have a binding issue that keeps the UI from updating the list of available devices.

Your best bet for help is to put your test project in a GitHub repo so others can take a look and spot where you may have gone astray.

I also tried this sample, after translating the strings to English. I tried it on my Note 8 and it works. But I am not sure what it is connecting to as I get only MAC Addresses for many of the devices. On Note 8 I often see similar lists with a description that "Name will be displayed once it is connected". And I don't know how to get the MAC Address of the BT devices that I have in hand. I tried with my Jabra earbuds for which the name is displayed. I start the pairing mode and try to connect through this app. The app reports it is connected but the pairing message continues in the earbuds and the phone also doesn't show as if it is connected. But once I refresh the list the Jabra is not listed.

@RavindraKumar Can u please give me suggestion how to start working on bluetooth printer implementing in my Xamarin forms application I found some samples and implemented in my app but not worked and I tried Zebra LinkOS multiplatform plugin but not worked in my app because of Xamarin forms package is 2.3.4.247
